What it detects

This rule detects a process named WerFault.exe running from a directory other than System32 or SysWOW64, a masquerading technique used by Turla Snake malware which hides in the WinSxS tree. The legitimate Windows Error Reporting binary only runs from system directories, so a WerFault image outside them is a high-confidence indicator of this masquerade and service abuse.
